To afwhom t my einem:

. citizen of the United States, residingA at y object of be rotative,

Los Angeles, inthe county 'of Los Angeles and State of California, have invented a new and useful Roller-Bearing, of which the following is a specification.

This invention relates to `roller-beisarings and is adapted to those bearings wherein the same rollers thattake radial pressures also take end thrust or lateral pressures, and an the invention is to produce a bearing for this purpose, of simple and cheap construction and easy to assemble.

lTh wherein means are'provided for'maintaining the position of the der end thrust or lateral pressures.

The invention further relates to such bearings wherein suchmeans are at a single end ofv the rollers. An object of the invention isto provide a roller bearing of this nature wherein the maximum number of rollers can be employed in a circular retaining. way of given diameter without resorting to unmechanical and unsafe expedients, such as split or segmental members, rings, lian es, tracks or rollers; or notches for one o more of the parts, which destroy the smoothness of the rolling parts. By means of the present inl vention all such complications are avoided and the rollers and bearing members `are made of si ple construction andare easy ,to assemble, at the same time the rollers are enabled to be brought so close together as to be substantially in continuity, thereby providing for the maximum number of rollers in a.given bearing.

The accompanying drawings illustrate the invention.v

Figure 1 is a partial longitudinal section of the view embodying the invention. Fig. 2 is a transverse section thereof on the line :v2-w? Fig. 1.

` The bearing comprises an inner member 1 and an outer member 2, either of which may the other being fixed, but said members may be provided with sleeve bearing members to take the wear, two sleeves `7, 7 being provided on the inner bearing member and two sleeves 8, 8' on the outer bearingmember. 3, 3 are provided, one set at each end of the bearing. Said bearing rollers run between specification of Letters Patent. Application led October 7, 1907. Serial No. 396,279.

.a single end thereof, V1 remote from the other set of bearing rollers, e invention also relates to bearings roller in the bearing, uni Two sets of bearing rollers CORPoEATIoN or 'ROLLER-BEARING.

the two sleeves 7, 8 at one end of the bearing, say the outer end, andare grooved or recessed at 5 near one end to receive an abutment ring or member 6 which extends into said recesses and rests against the outer end of the outer bearing ring 8. The outer end of each of the rollers of this set is adapted to engage laterally with an abutment flange l() formed on the inner bearing sleeve 7. At the other end of the bearing a'set of rollers 3 runs between the inner and outer bearing sleeves 7, 8

namely, the end most with a. recess or groove l5 to receive an abutment ring or member 6 which extends from the outer bearing member and rests against the end of the outer bearing sleeve 8. The inner bearing sleeve 7 has an annular Hange 10 engaging the end of bearing rollers 3 most remote from the bearing rollers 3. vThe above parts are all held in position by means of a nut 13 screwing on the inner bearin member 1 and engaging` with the outer end of the bearing sleeve 7, the parts being confined between a shoulder 14 on this nut and a shoulder 15 on the inner bearing member, and the end pressures being transmit-ted longitudinally between the bearing members and rollers by means of the abutments and recesses thereof, as hereinafter set forth.l A cap member 16 is the parts from dust. l

All radial pressures are taken by the bearing rollers 3, 3', and all'end thrusts or lateral pressures `are also taken by said rollers. Thus if the inner bearing member 1 tends to move to the right relatively to the outer bearing member 2, the flange `10 on the sleeve 7 engages with the inner end 4 of roller 3. The outer Wall 17 of the groove 5 of -said roller engages with the flange 6', the pressure thus being transmitted to the sleeve 8 and to the outer memberf2. On the other hand, if the inner bearing member 1 tends to move to the left with respect to theouter bearing member 2, the ange 10 of the sleeve 7 on the inner bearing member engages with the outer ends 4 of the outer set of bearing rollers 3 and the pressure 1s transmitted from` the outer "shoulder or face 17 of the groove 5 in said bearing rollers to the rin 6 and through sleeve 8 to the outer mem r 2. Thus one or the other set of rollers comes into action Patented June 2"?, 1911. i

and is provided near provided for protection of to resist end thrust according to the direction of the thrust. It Will be noticed that the rollers are of uniform diameter from end to end so that the points of end thrust eenn tact with rolling friction on members '7, 7".

With the above-described construction a condition of end thrust in the bearing does not materially displace the rollers notwithstanding that the rollers are loosely assemand outer bearing members, a set of bearingl rollers at each end of the bearing, each set forming a circular series otl rollers in close juxtaposition, each roller having a groove near that end which is most remote from the other set of rollers, abutment means ateach end of the bearing onone bearing member engaging with the end of the rollerslwhieh are most remote from the other set of rollv ers, bearing member extending into the recesses of the rollers and engaging with the Walls in andan abutment means on the other Y said reeel-ses which are most remote from the other of rollers.

2. A ro bearing eemprising inner and outer bee membe.'`r and rollers having a groove near ,",ngie end and having a uni- '.orm diameteL am end to end except for said groove, one et said bearing members having an abutment to laterally engage in said groove, and the` other of said bearing members having an abutment to laterally engage on the end of said rollersadj acent to said groove.

3. In a roller bearing 'comprising inner and outer bearing members, a set of caring rollers at each end of the bearing each roller having an end shoulder and a groove adjacent 'thereto to form another shoulder, l

whereby two shoulders are formed at a single endv of each roller, and tWo abutment means on eachV bearing member engaging laterally with saidjshoulder. Y

Intestimony whereof, I have hereunto set my hand at Los Angeles, California, this 1st day of October 1907.
